Get (by reference) the triangles that are inside the given edges, removing the outer boundary triangles If a Winding-Number-based fill mode is used, assumes edges are oriented and tracks the winding number across edges
true if the result was well defined and consistent; false otherwise. Solid fill mode always has a well defined result; Winding-number-based fills do not if the edges have open spans. Note the triangulation will still be filled by best-effort even if the function returns false.
